Abstract Emerging studies suggest that microRNAs (miRNAs) play multiple roles in cancer malignancy, including proliferation and acquisition of metastatic potential. Differentially expressed miRNAs responsible for the malignancy of lung cancer were searched by miRNA microarray using a previously established brain metastatic lung cancer model. Twenty-five miRNAs were down-regulated in brain metastatic lung cancer cells. Among those, miR-193b-3p and -5p were chosen for further studies. Their function in metastatic potential and proliferation was examined using Transwell invasion, wound healing, and colony forming assays. The underlying mechanism of tumor-suppressor miR-193b-3p and -5p was explored using reverse transcriptase quantitative polymerase chain reaction (RT-qPCR), Western blot, Argonaute 2-RNA immunoprecipitation (Ago2-RIP), and reporter assays. Both strands of miR-193b were down-regulated in brain metastatic lung cancer cells and in tissues from lung cancer patients. Overexpression of miR-193b-3p and -5p inhibited invasive and migratory activities and diminished clonogenic ability. Conversely, inhibition of miR-193b-3p or -5p increased the metastatic potential and colony forming ability. Cyclin D1 (CCND1), Ajuba LIM Protein (AJUBA), and heart development protein with EGF like domains 1 (HEG1) were identified as common target genes of miR-193b-3p and -5p. A reporter assay and an Ago2-RIP experiment showed that both miRNAs directly bind to the 3′ untranslated region (3′UTR) of the target mRNA. Knockdown of target gene reduced the proliferative and metastatic potential of primary and metastatic lung cancer cells. Our results demonstrate miR-193b is a dual-strand tumor suppressor and a novel therapeutic target for lung cancer.

Abstract Brain metastases are the most common intracranial tumors in adults and are associated with increased patient morbidity and mortality. Limited therapeutic options are currently available for the treatment of brain metastasis. We have identified an actionable signaling pathway utilized by metastatic tumor cells whereby the transcriptional regulator Heat Shock Factor 1 (HSF1) drives a transcriptional program, divergent from its canonical role as the master regulator of the heat shock response, leading to enhanced expression of a subset of E2F transcription factor family gene targets. We showed that HSF1 is required for survival and outgrowth by metastatic lung cancer cells in the brain parenchyma. Unexpectedly, we identified the ABL2 tyrosine kinase as an upstream regulator of HSF1 protein expression, and showed that the Src-homology 3 (SH3) domain of ABL2 directly interacts with HSF1 protein at a non-canonical, proline-independent SH3 interaction motif. Importantly, knockdown of ABL2 impairs expression of HSF1 protein and HSF1-E2F transcriptional gene targets. Notably, we found that pharmacologic inhibition of the ABL kinases using selective ABL allosteric inhibitors, but not ATP-competitive inhibitors, ablates the physical interaction between ABL2 and HSF1, leading to markedly decreased expression of HSF1, E2F1 and E2F8 proteins in brain-metastatic lung cancer cells, and depletion of HSF1-E2F transcriptional targets. These findings highlight potential differences affecting intra- and inter-molecular protein-protein interactions induced by allosteric versus ATP-competitive kinase inhibitors that have important therapeutic implications. Importantly, the targetable nature of the ABL2-HSF1-E2F signaling network identifies ABL allosteric inhibitors as a potentially effective therapy for the treatment of metastatic lung cancers characterized by high expression of HSF1.
